Application filed April 16, 1926. Serial No. 102,457.

This invention is an improvement in wrappers for shingle bundles and more particularly in a wrapper adapted to be folded about the bundle, and having in connection therewith integral reinforcements adapted to lie in sets beneath the tie wires when the wrapper is in place. a

In the usual method of shipping shingles of composition material, they are bound between boards in'a bundle of a selected number, the bundle including the boards being bound with flexible strands, such for instance as tie wires, the wires passed about the bundle near the ends of the long axis thereof.

This method of packing provides protection for two opposite faces of the bundle, and holds the individual shingles in place. However, the side and end faces of the bundle are unprotected, and the edges of the shingles are liable to injury during hanbundle to prevent cutting by the tie wires.

It is sometimes desirable and advisable to make use of a binder board of heavy material on one face of the bundle,-to stiffen the same 'in its long axis. When so used, it is obvious that the board provides a sufficient covering for one face of the bundle, and since the boards are of relatively heavy material, reinforcements are not necessary at the face covered by the board.

It is also" desirable in some instances to Vary the position of the tie wires, arranging them near to or farther from the ends, and as a consequence the reinforcing tabs must be in such relation to the wrapper that they willstill lie beneath the tie wires when the bundle is wrapped.

One of the primary objects of the present invention is the provision of a wrapper ca able of use with a binding board, and havmg all of the advantagesof the wrapper of the application above mentioned, with a minimum of material.

Another object is the provision of a wrapper wherein the eventual location of the sets of reinforcing tabs in the wrapped bundle may be varied by cutting the wrapper in a selected manner.

With these and other objects in view the invention consists in the construction and novel combination of parts fully described hereinafter, illustrated'in the accompanying drawings, and pointed out in the claims appended hereto, it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claims, may be resortedto without departing from the spirit of the invention.

In the drawings forming a part hereof:

Fig. 5'is a view similar to Fig. 2, of one end of the partly wrapped bundle.

Fig. 6 is a perspective view of the bundle with one tie wire in place.

Fig. 7 is a plan View of another embodiment, and

Fig. 8 is a detail in plan of another embodiment.

In the embodiment of the invention shown in Fig. 1, the improved wrapper, cut or otherwise formed from a web of suitable stock, includes a body portion 1 of rectangw lar outline, provided at its sides and ends with side and end flaps 2 and 3 respectively. Each of the side flaps 2 is provided at the edge remote from the body with a wing or extension 4. of the samelength as the flap, and of approximately the same width. Each of the end flaps 3 is provided with a relatively narrow extension 5 at the edge remote from the body, of the same length as the flap,

but of much less width.

7 The aggregate width of the wings or extensions 4 is approximately that of the width of the bundle, so that when the wrapper is folded the said edges will abut, although it is obvious that they may lap slightly if desired. In folding the wrapper about the bundle, the extensions 5 are folded beneath the extensions 4 as indicated in Fig. 2, and the said extension 5 need be of a width only sufficient to insure engagement beneath the ends of the side flaps 4.

At each end each end flap 3 is provided with a wing 5 usually a little less in length than the width of the adjacent side flap, and. each wing is provided at each side, and at its free end, with an integral tab 6, the tabs adjacent the flaps being cut from the said flaps as shown. The tabs 6 are at the corners Of the wings 5, and since the four wings are of the same length, and of a width equal to the depth of the bundle with the wrapper thereon, the tabs when the wrapper is folded about the bundle will extend beyond the corners of the bundle, and may be lapped about the corners beneath the tie wires 7 as shown in Fig. 3.

Due to the like dimensions of the wings and tabs, the tabs will lie in sets, in planes transverse to the bundle, near the ends there of and will lap about the corners for reinforcement at the points crossed by the tie wires. It is obvious that the position of the planes in" which the sets of tabs lie will be determined by the length of the wings 5. While it is evident that a binder board might be used with this construction of wrapper, it would be a'waste of-material, namely the portion of the wrapper beneath the board, and since one of the objects of the wrapper is economy similar constructions are shown in Figures 4; and 7, wherein the wrapper is of aggregate size to leave one side of the bundle exposed or partly exposed when in place thereon.

In Figure 4 the wrapper includes a body 8, side and end flaps 9 and 10, and wings 11 at the ends of the end flaps. Each wing 9 and 10 has an extension 12 relatively narrow, and if desired the corners of the extensions may be' mitered as shown at 13. Each of the wings 11 has an integral tab 14 at its inner fr ee corner, the said tabs being cut from the side flaps as shown. Since a'binder board is intended to be used with this construction, the extensions 12 are only wide enough to engage beneath the edge of the board, and since the board is of material sufliciently heavy to prevent cutting by the tie wires, no reinforcing tabs are necessary at that face of the bundle covered by the board. Hence the wings 11 have the tabs at their inner free corners only.

In placing the wrapper above mentioned, it is folded about the bundle as shown in Fig. 5, the extensions 12 engaging the upper face of the bundle atthe edges thereof,but not covering said face. The wings 11 are f0lded against the ends of the sides, and the tabs 14 will lap about the corners of the face remote from the board. Since the wings 11 are alike, the tabs 14 will lie in sets in planes transverse to the bundle, there being two tabs to the set instead of four as in the Fig. 1 construction.

The board 15 of any suitable material is of a size corresponding to that of the bundle face which it is designed to cover. The board is placed on the extensions 12 as shown in Fig. 6 and the tie wires 16 are passed about the bundle and the board at the planes occupied by the sets of tabs 1 1. The edges of the shingles and the wrapper are protected against cutting by the tie wires, at one. face by the tabs 14, and at the opposite face by the binder board. The wings 11 are held in place by the tie wires, as are also the side flaps, and the end flaps are held in place by the wings.

In the construction of Fig. 7 the blank includes a body 17, side and end flaps 18 and 19 respectively, wings 20 at the ends of the end flaps, and integral reinforces 21 at the inner free corners of the wings. That is the construction is substantially the same as that of Fig. at with the exception of the extensions .12 which are omitted from ,the side and end flaps. Thus there is a saving of material to this extent, while the wrapper is just as securely held in place. When the wrapper is folded about the bundle and the binder board is placed, the free edges of the side and end flaps abut the board. The tabs lie in sets of two in plan-es transverse to the bundle, and the side flaps are held in place by the wires. The end flaps are held by the wings, which in turn are held by the wires. The binder shown in Fig. 7 is the simplest form of the construction, containing a. minimum of material, and capable of being out from the web with a minimum of waste. No part of the web is wasted in the cutting of blanks in this construction.

As previously mentioned, the position of the reinforcing tabs with relation to the bundle is dependent upon the length of the wings. The wings may be of such length as to cause the tabs to lie in sets spaced at any desired distance from the ends of the bundles. Referring to Fig. 8 it will be noted that the blank 22 has wings 23 at the ends of its end flaps, which are of greater length than the width of the side flaps 25, extending nearly to the free edge of the wings or extensions 26 on the side flaps. The tabs 27 are cut from the wings or extensions 26, instead of from the side flaps. Tith this arrangement the tabs 27 will lie nearer the center of the bundle. It is obvious that the tabs might be placed nearer to the end flaps in any of the constructions shown if desired. They might be placed farther away in the Fig. 4 construction, but not in the Fig. 7 construction, without some waste of material.

In practice crease lines are provided in each construction between the body of the wrapper and the side and end flaps= Also between the said flaps and the extensions, be-
